NFR25, NFR25H www.vishay.com Vishay BCcomponents Fusible, Non-Flammable Metal Film Leaded Resistors FEATURES • Technology: metal film • Overload protection without risk of fire • Wide range of overload currents (refer Fusing Characteristics graphs) • Lead (Pb)-free solder contacts • Pure tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes DESCRIPTION A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps. The resistors are coated with a gray, flame retardant lacquer which provides electrical, mechanical, and climatic protection. The encapsulant is resistant to all cleaning solvents in accordance with IEC 60068-2-45. • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS • Audio • Video TECHNICAL SPECIFICATIONS DESCRIPTION NFR25 NFR25H Resistance range (1) 0.22 to 15 k 0.22 to 15 k Resistance tolerance 5% 5% E24 E24 Resistance series Rated dissipation P70 Thermal resistance (Rth) 0.33 W 0.5 W 240 K/W 150 K/W Temperature coefficient 0.22 R 4.7 ± 200 ppm/K ± 200 ppm/K 4.7 R 15 ± 200 ppm/K ± 100 ppm/K 15 R 15 k ± 100 ppm/K ± 100 ppm/K Operating voltage, Umax.

For ease of recognition a fifth ring is added, which is violet for type NFR25 and white for type NFR25H. OUTLINES The length of the body (L1) is measured by inserting the leads into holes of two identical gauge plates and moving these plates parallel to each other until the resistor body is clamped without deformation (IEC 60294). FUNCTIONAL PERFORMANCE, PRODUCT CHARACTERIZATION Standard values of nominal resistance are taken from the E24 series for resistors with a tolerance of ± 5 %. The values of the E24 series are in accordance with IEC 60063.

The tests are carried out in accordance with IEC 60068-2-xx test method, “Recommended basic climatic and mechanical robustness testing procedure for electronic components” and under standard atmospheric conditions according to IEC 60068-1, 5.3. Revison: 05-Oct-15 In the Test Procedures and Requirements table the tests and requirements are listed with reference to the relevant clauses of IEC 60115-1 and IEC 60068-2-xx test methods. A short description of the test procedure is also given. In some instances deviations from the IEC recommendations were necessary for our method of specifying. For inflammability requirements reference is made to IEC 60115-1. All soldering tests are performed with mildly activated flux.
